Falls said Walker had not contacted him before she and community activist Frank Matthews held today's press conference. Falls said he met with her and Matthews today for 45 minutes.

Normally, Falls said, the DA's office will not contact family members after a decision made not to file charges in a case. They never meet with family's of defendants and the facts of the case suggest Ja'Quares Cortez Walker -- had he survived -- would have been the only to be charged.

Birmingham police have said Ja'Quares approached a couple in an SUV as it pulled into the gated southwest Birmingham complex where a woman in the vehicle lived. He was wearing a T-shirt covering his face, and was brandishing a loaded and cocked pistol as he demanded them to get out of the car.

The driver pulled a gun and shot Ja'Quares multiple times, hitting him in the chest and abdomen. The teen was pronounced dead on the scene. Police refused to identify the man or woman in the car, saying only that the man who fired the shots was a 35-year-old white man.

Speaking after the meeting with Falls, Matthews said questions remain and he plans to contact Birmingham Police Chief A.C. Roper. Birmingham police spokesman Johnny Williams said today Walker only needs to contact Birmingham homicide detectives if she would like to discuss the case with police.

Matthews, who is black, questioned why the shooter waited until Ja'Quares -- whom Matthews described as a "tall, skinny black kid" -- was standing at his car to pull his own gun.

"I'm a black man and I'm pulling the gun before he gets to my car," Matthews said. Matthews speculated the shooting might have stemmed from a drug deal gone bad, but said he can't be sure until they have all the facts.

Walker, at today's press conference, said she wondered if the five teens with Ja'Quares put him up to the robbery.
